IMPROVEMENT IN ATTACHING'HUBS TO AXLES.

Specification forming part of Letters Patent No. 173,206, dated February8,1876; application filed July 3, 1875.

, inafter described.

A is the hub of the wheel. B is the axlebox, which is fitted into thebore of the hub A, and which,is made longer than the said hub A, so asto project at both ends. 0 is the axle-arm, which fits into the axle-boxB, and has a collar, D, formed upon its inner end. Upon the inner end ofthe axle-box B is formed an 0utwardly=projecting ring-flange, b, whichrests against the collar D, and interlocks with 4 an inwardly-projectingring-flange, 0, formed upon the inner end of the sleeve or band E.

When the band E is to be applied to an old axle, the pin F may beemployed to fasten it and the screw-thread dispensed with.

Upon the outer, surface of the projecting outer end of the axle-box B iscut a screwthread, into which fits a screw-thread formed upon the innersurface of the cap-nut G. The cap-nut G projects outward, and has arecess formed in it to serve as 'a. reservoir for the oil, and has ahole formed through it, leading into its cavity, through which the oilmay be poured,

and which is closed by 'a screw or other plug, g The nut G has aring-flange, formed j around it, which'rests against the outer hub- Vband H. The inner hub-band I projects over .a part of the band E, asshown in the figure.

In the axle-arm (J is formed a spiral groove, 0, to conduct the oil fromthe reservoir in the nut G along the entire length of the axlearm 0..

By this construction the oil cannot get out,-

and dirt and sand cannot get in to wear the axle-arm G and the axle-boxB.

Having thus described my invention, I claim as new and desire to secureby Letters Patent The combination of the threadedband E with theaxle-box B, having corresponding and interlocking ring-flanges b e, andthe axle having enlarged threaded collar D, as

shown and described, forthe purpose specified.
